Question 440147
y=mx+b


{{{y=(2/5)x+4}}}


Clear the fraction by multiplying both sides by 5:

{{{5y=2x+20}}


To get the x and y terms on the same side, subtract 2x from each side:

{{{-2x+5y = 20}}}


Now, the tradition in math is to keep the x coefficient positive, so multiply both sides by -1:

{{{2x-5y = -20}}}
